Layout and application information
For Optim um Jitter Perform ance, Pletronics recom m ends:
•
a ground plane under the device
•
no large transient signals (both current and voltage) should be routed under the device
•
do not layout near a large m agnetic field such as a high frequency switching power supply
•
do not place near piezoelectric buzzers or m echanical fans.
